Effects of drought and cytokinin pool size on growth rates of Arabidopsis plants. The growth rates of individual Arabidopsis lines recorded during the drought stress and recovery period and of their respective controls were analyzed by principal component analysis (PCA). The PCA clearly separates the drought stressed plants from the control groups along the PC2, and PC1 illustrates a similarity in the growth rate dynamics between lines with the constitutive and inducible CKX expression.
